PROBLEM TO BE SOLVED: To provide an efficient interface that would allow for the use of polymeric windows in applications where hoop load bearing is desired considering a fact that the polymeric windows are not as mechanically strong as glass windows and are not used in hoop loaded applications.SOLUTION: An aircraft transparency includes a first layer having a first major surface and a second major surface. A second layer is spaced from the first layer and has a third major surface and a fourth major surface. A polymer intermediate layer is positioned between the first layer and the second layer. At least one hole extends penetrating through the first and second layers and the intermediate layer. A bush having high strengh is positioned in the hole and has an outer side wall which is in direct contact with materials of the first and second layers. In one embodiment, the hole is a tapered hole and the bush has a tapered outer side wall. In another embodiment, the hole is a cylindrical hole and the bush has a cylindrical outer side wall.SELECTED DRAWING: Figure 2 |
